Application filed March 3, 191?, Serial No.71529. Renewed March 15, 1919. Serial No. 282,962.

To all 'Lo/Lone, t may concer/a.'

Be it known that l, Grenen C. Danny, a citizen of the United States, and resident of Springdale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Glass-Drawing Baits; and l do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to baits for drawing glass cylinders.

ln the drawing of glass cylinders where a bait is lowered into a body of molten glass and then gradually raised while air is admitted to the interior of the cylinder in order to hold it out to the proper. diameter, it is usual to have the `bait `permanently secured to the blow-pipe and this blow-pipe is suspended from a vertically-traveling cage, so that when the cylinder has been drawn and it is desired to lower the same, the bait and blow-pipe `are disconnected from the cage and as the cylinder is lowered, the cylinder is moved out at an angle so that when brought down into position to rest upon the horse, the cylinder is in a horizontal position with the blow -pipe and the bait still. attached thereto. 'lhe cylinder is then cut up by cutting it circumferentially into suitable lengths, but before` this is done, the cylinder is capped olif at a point adjacent to the bait, so as; to relieve the cylinder from the strain due to the bait in addition to the `weight of the blow-pipe rlhe weight of the blow-pipe sometimes creates such a strain on the cylinder after it has been lowered onto the horse as to cause it to break the cylinderat some distance from the bait, thereby causing considerable loss.

The object of my invention is to Vprovide means for `disconnecting the bait from the blow-pipe after the cylinder `has been lowered onto the horse, so as `to relieve the cylinder of the weight of the blow-pipe and so reduce the liability of breakage.

To these ends my invention comprises the removable bait which may be readily freed from connection with the blow-pipe, all as fully hereinafter set forth and claimed.

ln the drawing, Figure 1 is a view of my improved bait with a portion of a cylinder attached thereto showing the position of the parts duringthe drawing of the cylinder; Fig. 2 is a view showing the position of the parte when the cylinder is lowered to horizontal position; Fig. 3 is an enlarged plan view partly in section; Fig. d is an enlarged cross-section; Fig; 5 is a section on the line w, Fig. 3.

Referring to the drawing, the numeral 2 designates a suitable arm or support which is connected up with a raising and lowering' device by i'neans of which the arm is moved up and down, said arn'i having the seat 3 to receive the trunnion or pin lf on the blowpipe ln this manner, the blow-pipe is suspended from the arm 2 and said blowpipe is adapted to swing in the seat 3, even to a horizontal. position as shown in Fig.

The lower end of the blow-pipe is secured to the plate or drawing head G with the guide lugs 7 formed on the inner `face thereof adjacent to the `periphery of the said plate. The blow-pipe o may be threaded into the threaded collar S on said plate, as shown in Fig. Ll.

rl`he plate G has the lugs 9 formed at opposite sides thereof, said lugs having the slots 10 formed therein through which the bolts 11 pass, said bolts passing through the arn'is 12, held between the pairs of lugs. The

outer ends of the ari'ns 19. vare connected up by the rod 13, the nuts 14 acting to secure said arms to said rod.

lThe arms 12 have the cani portions 12e which are adapted to bear against the plate 6 for the purpose fully hereinafter set forth.

rlFhe `latches 15 are mounted to swing on the 'bolts 11, said latches having notches 16 adapted to engage the pins 17 on the bait 18.

l/Vhen the bait 18 is attached to the plate 6, the notches 1li in the latches 15 engage the pin 17 and hy moving the arms 1:2 the cani `portions of said arms act to pull up on the latches 15 and so securely bind or fasten the bait 18 to the plate 6.

To provide for the automatic release of ico to the plate 6. After the cylinder has been drawn and it is desired to lower saine, the arm 2 supporting the blow-pipe and cylinder is lowered, and as said arm is lowered the cylinder is swung out at an angle and isvlinally brought down to a horizontal position as indicated in Fig. 2, in order to bring it into position upon the horse which is to support it during the operation of capping and cutting it up into suitable lengths. lt

- will be apparent that by this lowering operation the blow-,pipe 5 will be gradually brought to a horizontal position as indicated in Fig. 2, and in so doing the rod 19 and arm 20 act on the principle or' a toggle so that the arm 20 is moved over into position to engage the rod 13 and will act to move said rod, thereby moving the arms 12 and freeing the latches 15 so that said latches are free to swing out of engagement withv the pins 17 as shown in dotted lines Fig. 2, whereby the bait is released from the plate 6 and the blow-pipe cangbe swung out of the way, leaving the bait alone attached to the cylinder. Or the cylinder with the bait may be withdrawn from the plate, as indicatedin dotted lines, Fig. 1n either event, the cylinder is relieved when lowered of the weight of the blow-pipe and that, too, automatically, while at the same time, the danger kof the breaking of the cylinder due to the weight of the blow-pipe is practically eliminated, and a great saving is thus etiected in the output. After the cylinder has been cappedoil adjacent to the bait, the bait is then in 'position toV beused again and is attached tothe plate 6 in the way above described by means ofthe latches 15 which are locked securely in place by the arms 12.

What I claim is: y '1. The combination ot avei'tically-niovable support, a blow-pipe suspended thereypipe from its support.

from,a bait detachably secured to the lower end of said blow-pipe` and means for releasingy said bait, said means being put in operation by the swinging of said blow-pipe from its. support.

2. The combination of a vertically-inevable support, a blow-pipe suspended therefrom, 'a plate carried byV said blow-pipe, a bait detachably connected to said plate, and means for v'releasing said bait put yinto operation by the swinging` movement of said blow- 3. `The Acombination of a vertically-movable support, a blow-pipe suspended therefrom, aplate carried by said blow-pipe, a

bait, latches carried by said plate engaging said bait, and means put in operation by the swinging of said blow-pipe from said support to release said latches.

5. The combination of a vertically-n'iovable support, a blow-pipe suspended therefrom, a plate carried by said blow-pipe, a bait, latches carried by said plate engaging said bait, locking mechanism for said latches, and means put in operation by the swinging of said blow-pipe from said support to unlock said locking mechanism.

6. The combination of' a vertically-niovable support, a blow-pipe suspended therefrom, a plate carried by said blow-pipe, said plate having slotted lugs, cam arms, pins passing through said slotted lugs enga-ging said arms, latches carried by said pins, a bait, pins on said bait engaged by said latches, a rod connecting said arms and means put in operation by the swinging ol said blow-pipe from its support for freeing said cam-arins.

7. rlhe combination olf a vertically-nlovable support, a blow-pipe suspended therefrom., a plate carried by said blow-pipe, a bait, latches carried by said plate engaging said bait, means carried by said plate for locking` said latches, and means carried by said support and said blow-pipe moving into engagement with locking means when said blow-pipe swings in its support, whereby said locking means is operated to releasesaid latches.

8, A combination of a vertically-niovable support, a blow-pipe suspended therefroin, a plate carried by said blow-pipe, locking arms on said plate, latches carried by saidv plate, a bait engaged by said latches, and toggle acting levers carried by said support and blow-pipe adapted by the swinging of said blow-pipe in its support to release said locking arms.

ln testimony whereof, I the said GEORGE C. DEBAY, have hereunto set my hand.
